Could install reject serial # due to being W7?

I bought a somewhat old game, Ghost Recon advanced warfighter 2. It says vista and XP, but i figured since i have installed a dozen older games no reason this wouldn't work. But it will not accept the serial number it came with. It says it's invalid, and i tried every way of typing it,m even with and without the dashes. I'm 100% positive it's not user error. I also tried vista and XP compatibility mode and ran the exe as admin. Any ideas?

Nevermind.....just found one that works via google. I also found the reviews on i think it was newegg showed most everyone who bough it had the same problem.
